APPARATUS FOR PREPARING EXTRAGTS.

a into contact with a=charge ofzmaterial for the ,purpose of producinganinfusion. j"

One practical embodiment of. the invention.

consists in a-portable structure for; preparing beverages, such as-aninfusion ofcoflee, tea or the like, althoughit shouldbe understood. thatthe invention is not-confined to. this specific use. I

The object of the invention is to automatic ally cut oil the sup ly ofheat upon the production. of a. pre etermined or desired. qipantity of aliquid extract or. infusion, t ere'by, effecting economyinthe-consumption of the fuel. and; obvlating attention to the 0.era'tion'of the-a paratus.

Re erence is to be he to the accompanying dIaw-ingmwhereinthe figure reresents-a V61:- tical sectional elevation, taken ongitudina-lly. throughone-embodiment offthe invention.

As shown by the drawings, my invention.

'is embodied as a portable urn adapted for use by families, hotels,restaurants, or the like. The apparatus is shown as having a. tank A,which may be-made of. metal, and in the form of a cylinder, theends ofwhichi are closed by suitable heads a." I, do nor desire, however, toconfine myself strictly to this particular form of. vessel, norto.metalin the constructionof the vessel, because the sha e ofthe vessel may bemodified. at; will an the other materials may be'used initsconstruction. In some instances, 1 may use a porcelain vessel, which maybe covered by aimetallic jacket; but as this is an obvious expedient, Ihave not thought it necessarytoillustrate the same in the drawing.

The tankA is arranged in a horizontal position, and itjis mounted on asuitable base B .inaway to have a tilting movement thereon.

Specification of Letters Patent. Application filed. January 24, 1905.Serial No. 242,527.

The base may be stationary or movable, but

as-shown, the base is provided with suitable Patented March 10, 19085bearings b, for axles b, which are with carrying Wheels V. Theparticular.

form of-the base, however, may be-modified! or changed at pleasure. Asonemeansfon pivotally mounting the vessel on the base, I employ avcranked axle a, adapted. to Work. in bearings a on the base, said vesselAbeing; tiltable, as indicated by full and dotted lines in the drawings.

The interior of the tiltable vessel is die videdzby. a partition c,,intoa liquid chamber, C, and an infusion chamber (1*.

The-bott0m.-ofthe tankA below the-liquid: chamber (3, is deflectedupwardly as at. d,. andbelow this deflected part of. said tank is.

arranged aheater D, the latter being sup? ported orcarried by the baseB. Said heater,

is represented as avapor lamp havin r a.wick.- The.

tube (1 inzwhich is arranged a wick flame-from the vapor lamp isdirectedagainst the deflected part (1 of the vessel, so as to heat theliquid in the compartmentv C. The heater ls adapted to be cutoff orthrownout of: service-by any suitable form of movable closure, but asherein represented, this cut ofi'is em'bodiedin the formof apivotedcover. D, which is adaptedtoelose over; the wick,

and thereby extinguish the -flame, seats toeut the heaterout ofserviee.

Water or other liquid may beintroduced.

conveniently into. the compartment. C through a. funnel e, which may besecurely. closed; by any suitable form of closure-e. The steam pressurein the chamber C may be reduced bya suitable form of automatic vent,such as e, having communicationwithsaid. chamber.

To prepare the infusion, .I employ adevice Which-I term an extractor,the same having communication with the infusion chamber C ofthe vessel,and also having communica: tion with the liquid chamber C this last inentioned communication being established by a pipe E. As shown by thedrawing, the feed pipe consists of two lengths arranged within thechambenC and extending into the extractor. The horizontallength of thefeedpipe extends through the partition 0, to have communication with thechamber C, whereas the vertical length pipe E extends beyond the chamberC and into the extractor.

equipped- ()n the upper side of the tank A is a collar f, havingconnnunication with the chamber C and the upper part of this collar isprof on the vessel A, because vertical length of said chamber C of theapparatus,

vided with a flange which constitutes a seat for the extractor vessel F.This extractor vessel may be made of glass, porcelain, a porousmaterial, or any other suitable substance, and at its lower part saidvessel has a hollow neck portion f which is titted snugly within theupstanding neck f of the tiltable vessel A. Within the lower part-of theex tractor vessel l is a foraminous bottom G, on which is adapted to beplaced the charge of material from hich the extract is to be prepared.The foraminous bottom is held in place by a depending flange g, whichfits within the hollow neck f, and from the middle part of this bottomGr rises a guide tube 9, the latter extending upwardly into theextractor vessel F. The vertical length of the feed pipe E passesthrough the necks f, f", and the tube g, the upper extremity of saidfeed pipe terminating above said tube g. A cap H is'screwed or otherwisedetachably connected to the upper protruding end of the feed pipe and inthis feed pipe is rovided one or more exit openings h, where y theliquid supplied to the feed pipe by the chamber C finds its exit throughthe openings h into the vessel of the extractor. The vessel F isfurthermore provided in its crown with an opening i, which enables thecharge of material to be readily introduced into the extractor, and thisopening is normally closed by a suitable 'form of cover I.

The extractor or percolator is adapted to be removed bodily from theshort tube or nipple the receptacle F and the perforated bottom G may bereadily Withdrawn from the tube or nipple f, it only being necessary toremove the cap H from the feed pipe E, when it is desired to withdrawthe bottom G, and its tube q from the feed E.

The feed pipe extends through the extract thereby housing said feed pipewithin a heated chamber of the apparatus, and preventing the liquidcontained in said pipe from cooling by contact with the externalatmosphere during the operation of transferring the liquid from thewater chamber C into the receptacle F of the 'percolator.

Another advantage of my invention is that the vertical branch of thefeed pipe extends upwardly from the extract chamber into the receptacleF of the pereolator, the arrangement being such that the percolator andits bottom G may be withdrawn from the vessel A, without disturbing orinterfering with the pipe E, whereby provision is made for easily andquickly cleaning the apparatus.

J designates a lever, which is arranged within the base and below thetiltable vessel A' This lever is hung or supported inter mediate of itslength by a rod j, supported by the base B.

The lever is hung to provide two arms, one

of which is longer which is 1 than the other, and as shown, the long armof said lever tits below the closure 1) of the I heater when saidclosure is swung to a posi- 1 tion where the wick is uncovered. Theshort arm of the lever tcrmiimtes close to l the tank A, and said leveris held in .in inl clined position by the long arm thereof being heavierthan the short arm.

The infusion stored in the chamber C is adapted to be drawn therrd'romat will through a suitable draw-otf cock or faucet K. it will beobserved that the extractor is mounted on the vessel A, near the endportion thereof, so that the extractor is movablebodily with said vesselin the tilting adjustment of the latter, and in order that the vesselmay take a lmrizontal position, .l pivotally mount it ecccntrically onthe base. The vessel is adapted to rest at one end on a suitable shelfor ledge lei.

L The operation. of the apparatus may be described as follows: Asuitable quantity of liquid is introduced into the chamber C, and theclosure 6 is applied to the filling opening. The cover I is removed fromthe vessel F, and a suitable quantity of tea or coffee, or othermaterial, is placed in the vessel F, the cover 1 being replaced. Thecut-oil l) of the heater is now moved to the open position shown by thedrawing, in cut-oil rests on the free end of the operating lever J. Amatch or taper is now applied to the wick d and the heat is directedagainst the bottom (I for the purpose of heating the liquid in thechamber 0. When the steam in the chamber attains the desired n'essure,the water is forced through the pipe. *1, and is discharged through theopenings It, upon the material contained in the vessel l. An infusion isprepared by bringing the hot liquid into contact with the charge ofmaterial contained in the vessel F, and the infusion is f rec to tlowthrough the bottom (it, and the ilange. 9, into the chamber This 0)eration con tinues until the weight of the iquid in the chamber C isbver-balanced by the quantity of infusion or extract stored in thechamber C When the desired quantity of extract is present in saidchamber C, the vessel A is tilted on the pivot a, to the positionindicated by dotted lines in the drawing, whereupon the lever J isactuated by the movement of the vessel, so as to turn the cut-off D to aclosed )osition over the wick (1?.

This automatically extinguishes the llame of the heater and throws theheater out of 1 service, whereby the fuel is saved and the l owner isrelieved from the necessity of l closely watching the apparatus.

t It is evident that the extractor F and the t bottom G maybe readilydetached from the vessel A. To do this the deflector ll should bedisconnected from the tube l), and the ,bottom G with the tube g, maythen be l slipped over the upper part of the feedzpipc l withoutdeparting from thes int of ole in-q I fairly'falll within the scope ofmyinvention.
